To all whom t may concern.'

Be it known that I, MAX NATHAN, Aa citi'- zen of the United States, and a resident of Ridgefield Park, in the county of Bergen and State of New Jersey, have invented certain new and useful improvements in Display Devices, of which the following is a specification.

This invention relates to a display device, and is particularly adapted to display, faceted or carbuncled stones or the like, and for any object that can be held in place by the device.

The organization of the invention comprises prongs of pliable or resilient material with which the stone or other object can be easily locked in position. Some of the materials used for the device are rubber, celluloid, aluminum, cork 0r the like.

The accompanying drawings show some of the forms of the invention, and many other forms thereof may be constructed and used without departing from the spiritof the invention.

Figure 1 represents a plan view of one form of the invention; Fig. 2 shows a section of Fig. 1 on the line 2, 2; Fig. 3 shows a plan view of a second form of the invention; Fig. 4 is a section of Fig. 3 on the line 4, 4; Fig. 5 shows a plan view of a third form of the invention and Fig. 6 shows a section of Fig. 5 on the line 6, 6.

Referring to Figs. 1 and 2 the device is shown to comprise a gripping block 40 of pliable material, like rubber or the like and in which are formed a number of central openings which may be of the same diameter or of different diameters as shown. A central opening 41 is shown with the four openings 42, and the combination of the latter openings with the central openings form the four pliable gripping prongs 43. ln the latter are formed the gripping grooves 44.

A second central opening 48 has formed therewith the openings 49, and there results the two gripping prongs 50 with the gripping grooves 51.

A third central opening 54 has formed therewith the openings 55 which form the three gripping prongs 56 with the gripping grooves 57.

A fourth central opening 60 has formed therewith the five openings 61, which form the five gripping prongs 62 with the gripping grooves 63. To use this second form of the invention, the pliability of the material coacting vwith the openings between the prongs permits the user to locate and dislodge a stone from the gripping grooves from either side of the block 40. l Referring to Figs. 3 and 4, the invention is shown to comprise two sheets of material 80 preferably of card boardV and between which is secured by means of cement or any other suitable fastening device a sheet 81 of a resilient material like Celluloid. ln each of the sheets of material 80 are formed one or a plurality of openings 82 which latter may be of the same or different sizes and shapes. The openings 82 in this instance are shown round and of the same diameter.

In the sheet 81 are formed central openings 83 which may be of the same or different diameters. With each central opening 83 are formed two or more openings 84 to form two or more gripping prongs 85 with the gripping grooves 86. The openings 82 are larger in diameter than the distance between the outer edges of their accompanying openings 84, to permit the gripping prongs 85 to spring when a stone or other object is inserted in the gripping grooves 86. rllhis last form of the invention is used in a manner similar to that described for Figs. 4 and 5.

The form of the invention in Figs. 3 and 4 may be further modified by eliminating one or both of the sheets of material 80, and using only the central sheet 81 of resilient material with its central openings 83 and the prongs formed with the latter.

Referring to Figs. 5 and 6l the invention comprises a sheet of resilient material 95 in which are formed central openings 96 and 97. Openings 98 join with the central opening 96 and form the prongs 99. The prongs 99 carry the little projections 100 to increase the thickness thereof and which have formed therewith the gripping grooves 101.

The central opening 97 has joined therewith the openings 105 to form the prongs 106 and the latter have'formed therewith the gripping grooves 107.

A sheet of material 110, preferably cardboard with the openings 111 is fastened to one side of the sheet 95 and a sheet of material 112 preferably cardboard with openings 113 is fastened to the other side of the sheet of material 95. The number of openings 96 and 97 with their coacting elements may be increased.
